Referring to FIGS. 1-2B, in the present embodiment, a supporting assembly 100 is assembled with a portable electronic device 10, wherein the portable electronic device 10 may be a tablet computer, a smartphone, a display device, all-in-one (AIO) computer, or other devices, and the portable electronic device 10 can stand on a working plane 20 via the supporting assembly 100. Generally, the supporting assembly 100 is disposed on a back cover of the portable electronic device 10, namely, a display screen is disposed at one side of the portable electronic device 10 and the supporting assembly 100 is disposed at another side. The supporting assembly 100 includes a stand 110 and a positioning module 120, wherein the portable electronic device 10 has a groove 11 accommodating the stand 110. When the stand 110 is in a folded state, the stand 110 can be folded into the groove 11, so as to maintain the appearance integrity of the portable electronic device 10.

The stand 110 is connected to the positioning module 120, wherein the number of the positioning modules 120 is two, the two positioning modules 120 are symmetrically disposed at the portable electronic device 10. As shown in FIG. 2A, the stand 110 is a U-shaped stand and connected to two positioning modules 120. Each of the positioning module 120 includes a carrier 121, a first rod 122, a first guiding element 123, a second guiding element 124, at least one position-limiting element 125, and at least one elastic element 126, and the number of each of the position-limiting elements 125 and the elastic elements 126 is schematically depicted as two in the drawings. The carrier 121 is fixed to the portable electronic device 10, the first rod 122 penetrates through the carrier 121 and is able to rotate with respect to the carrier 121. In other words, the first rod 122 is pivoted to the carrier 121. On the other hand, the stand 110 is fixed to the first rod 122, the first guiding element 123 is fixed on the first rod 122, and the second guiding element 124 is movably disposed on the first rod 122. The second guiding element 124 and the stand 110 are respectively located at two opposite sides of the first guiding element 123, wherein the first guiding element 123 and the second guiding element 124 are coupled to each other, and the second guiding element 124 is able to move back and forth on the first rod 122 along a direction D.

More specifically, the carrier 121 has a first position-limiting portion 121 a, a second position-limiting portion 121 b, and a third position-limiting portion 121 c, and the second position-limiting portion 121 b and the third position-limiting portion 121 c are located at the same side of the first position-limiting portion 121 a. The first rod 122 penetrates through the first position-limiting portion 121 a, the first guiding element 123, the second guiding element 124, and the second position-limiting portion 121 b, wherein the first position-limiting portion 121 a is located between the stand 110 and the first guiding element 123, the first guiding element 123 and the second guiding element 124 are located between the first position-limiting portion 121 a and the second position-limiting portion 121 b, and the first guiding element 123 is located between the second guiding element 124 and the first position-limiting portion 121 a. In other words, the second guiding element 124 is configured to move back and forth between the first guiding element 123 and the second position-limiting portion 121 b.

In the present embodiment, the positioning module 120 further includes a second rod 127 penetrating through the first position-limiting portion 121 a, the second guiding element 124, and the third position-limiting portion 121 c. The first rod 122 and the second rod 127 are arranged in parallel and separately penetrate through the second guiding element 124, thereby increasing the stability of the second guiding element 124 when moving back and forth along the direction D and preventing the second guiding element 124 from rotating with respect to the carrier 121. The first guiding element 123 has a positioning portion 123 a, wherein the second guiding element 124 has an engaging portion 124 a, a locking portion 124 b, and an inclined portion 124 c connected to each other, and the locking portion 124 b is located between the engaging portion 124 a and the inclined portion 124 c. When the stand 110 is received into the groove 11, the positioning portion 123 a is engaged with the engaging portion 124 a, so as to prevent the stand 110 from being unintendedly rotated with respect to the carrier 121 (or the portable electronic device 10).

The position-limiting element 125 is disposed at a side of the second guiding element 124, and the second guiding element 124 is located between the position-limiting element 125 and the first guiding element 123. As shown in FIG. 2B, the position-limiting element 125, the second position-limiting portion 121 a, and the third position-limiting portion 121 b are located at the same side and actually arranged to form a straight line. The elastic element 126 is a compression spring that leans against the position-limiting element 125 and the second guiding element 124. In the present embodiment, the positioning module 120 further includes at least one third rod 128, wherein the number of the third rods 128 is corresponding to the number of the position-limiting elements 125 and the number of the elastic elements 126, and the third rod 128 penetrates through the first position-limiting portion 121 a and the second guiding element 124. The position-limiting element 125 is connected to one end of the third rod 128 that penetrates through the second guiding element 124, wherein the elastic element 126 is sleeved on the third rod 128 and is positionally limited between the second guiding element 124 and the position-limiting element 125.

FIG. 3 is a schematic side view of a stand in FIG. 1 expanding to a first angle to make the portable electronic device stand on a working plane. FIG. 4 is partially enlarged view of the supporting assembly in a state shown in FIG. 3. Referring to FIGS. 3-4, when a force is applied to the stand 110 to make the stand 110 rotate with respect to the carrier 121 (or the portable electronic device 10) along a rotating direction R, the first guiding element 123 rotates together with the first rod 122 and drives the second guiding element 124 to move closer to the position-limiting element 125 and along the direction D (as depicted in FIG. 2B), so as to compress the elastic element 126. At this time, the positioning portion 123 a departs from the engaging portion 124 a and moves to the locking portion 124 b, so the stand 110 expands to a first angle A1 with respect to the portable electronic device 10. Accordingly, the portable electronic device 10 and the stand 110 in the expanded state form at least two supporting points, so the portable electronic device 10 can stand on the working plane 20 at an angle that the user can view. In detail, a force applied to the stand 110 by the weight of the portable electronic device 10 can make the positioning portion 123 a lean against the locking portion 124 b, so as to keep the elastic element 126 in a compressed state.

FIG. 5 is a schematic side view of the stand in FIG. 3 expanding from the first angle to a second angle to make the portable electronic device stand on the working plane. FIG. 6 is partially enlarged view of the supporting assembly in a state shown in FIG. 5. Referring to FIGS. 5-6, the user can apply a force to the portable electronic device 10, so as to make the stand 110 continue to rotate with respect to the carrier 121 (or the portable electronic device 10) along the rotating direction R. At this time, the first guiding element 123 rotates together with the first rod 122 and drives the second guiding element 124 to move along the direction D (as depicted in FIG. 2B) and towards the position-limiting element 125, so as to further compress the elastic element 126. Therefore, the positioning portion 123 a moves from the locking portion 124 b to the inclined portion 124 c, so the stand 110 expands to a second angle A2 with respect to the portable electronic device 10, wherein the second angle A2 is greater than the first angle A1. Accordingly, the portable electronic device 10 and the stand 110 in the expanded state still form at least two supporting points, so the portable electronic device 10 can stand on the working plane 20 at another angle that the user can view. In detail, a force applied to the stand 110 by the weight of the portable electronic device 10 can make the positioning portion 123 a lean against the inclined portion 124 c, so as to keep the elastic element 126 in the compressed state.

In the process of the stand 110 being rotated with respect to the carrier 121 (or the portable electronic device 10) along the rotating direction R, the positioning portion 123 a sequentially moves along the engaging portion 124 a, the locking portion 124 b, and the inclined portion 124 c. On the contrary, when the user moves the portable electronic device 10 away from the working plane 20, the elastic potential energy stored when the elastic element 126 is compressed is released to drive the second guiding element 124 to move away from the position-limiting element 125 and along the direction D (as depicted in FIG. 2B). At this time, the first guiding element 123 is driven by the second guiding element 124 to rotate in a reverse direction of the rotating direction R, and the positioning portion 123 a can sequentially moves from the inclined portion 124 c through the locking portion 124 b to the engaging portion 124 a, so as to drive the stand 110 to rotate with respect to the carrier 121 (or the portable electronic device 10). Therefore, the stand 110 returns into the groove 11, so the elastic element 126 returns to the state shown in FIG. 2B.

In summary, the supporting assembly of the invention is integrated into the portable electronic device, wherein the stand is able to be rotated with respect to the portable electronic device through the positioning module so as to transform from a folded state to an expanded state, so an angle between the portable electronic device and the stand has different values. Accordingly, the portable electronic device and the stand in the expanded state form at least two supporting points, so the portable electronic device can stand on the working plane at different angles that the user can view. Therefore, the supporting assembly of the invention improves the convenience in operation.
